DC Solar Photovoltaic Cables
Solar cables are exclusively made for applications in photovoltaic power systems. A solar cable interconnects solar panels and other electrical components of the photovoltaic system. DC Solar Cable are single core copper cables each for +ve and -ve, They are insulated with cross linkable Low Smoke Zero Halogen compound and sheathed with Low Smoke Zero Halogen compound (Conforming to BS EN 50618:2014 Standard)
Special Properties Of Solar Cables
- Lasts up to 30 years even under tough external conditions.
- Resists extreme temperatures (-40°C to 120°C maximum at the core) and ozone resistant.
- Full protection against ultraviolet rays.
- Low smoke emission & low toxicity/corrosivity during a fire.
- Flame retardant, fire retardant.
- Suitable to common connector types.
- Electron-Beam & Silane Cross Linked
